Issue #19147 has been updated by vo.x (Vit Ondruch). Testing further, there might be issue in some other places. While I can't reproduce the issue on Fedora Rawhide, it still fails on Fedora 38. I was not expecting this. Might the culprit be e.g. glibc? Or is it FS type related? ---------------------------------------- Bug #19147: `TestFileExhaustive#test_expand_path_for_existent_username` and `TestDir#test_home` fails on i686 https://bugs.ruby-lang.org/issues/19147#change-105533 * Author: vo.x (Vit Ondruch) * Status: Closed * Priority: Normal * ruby -v: ruby 3.2.0dev (2022-11-24 master 66e5200ba4) [i386-linux] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- Testing with commit:git|66e5200ba4 on Fedora Rawhide, I observe following error just on i686 (other platforms are passing just fine): ~~~ 1) Error: TestFileExhaustive#test_expand_path_for_existent_username: RuntimeError: can't set length of shared string /builddir/build/BUILD/ruby-3.2.0-66e5200ba4/test/ruby/test_file_exhaustive.rb:1122:in `expand_path' /builddir/build/BUILD/ruby-3.2.0-66e5200ba4/test/ruby/test_file_exhaustive.rb:1122:in `test_expand_path_for_existent_username' 2) Error: TestDir#test_home: RuntimeError: can't set length of shared string /builddir/build/BUILD/ruby-3.2.0-66e5200ba4/test/ruby/test_dir.rb:537:in `expand_path' /builddir/build/BUILD/ruby-3.2.0-66e5200ba4/test/ruby/test_dir.rb:537:in `block in test_home' ~~~ Previously testing with commit:git|4b1504ae0a, the tests were passing just fine. -- https://bugs.ruby-lang.org/
